- •
Metal bioaccesibility and size distribution are different in smelting and mining area.
- •
Consider particles <50 μm to avoid underestimating exposure to children.
- •
Gastric bioaccessibility varies according to particle size but not linearly.
- •
Modelization of particles deposition in lungs refines exposure assessment.
- •
Contribution from oral or inhalation to internal exposures depends on the metal.
